It is based on TDS-OFDM (Time Domain Synchronous – Orthogonal Frequency Division Multiplexing) modulation, a development of DVB-T OFDM, and much more complex than ATSC (8VSB).
The new technology allows the application of modulation (similar to regular OFDM) multi-channel transmission, which is necessary for the transmission of large data streams, especially for HDTV. Advanced TDS-OFDM modulation also improves the transmission parameters through time-domain division.
